SPECIFICATION forming part of Letters Patent No. 446,773, dated February 1'7, 1891.

Application filed May 21,1890. Serial No! 352.605. (No model.)

To aZZ whom, it may concern: is held a self-reversing knife J, secured on Be itknown that 1, JOHN W.

The wheel in revolving in the opposite direction causes the paddles II to throw the snow to the other side of the track. 13y constructing the wheel as described great strain at the center of the wheel, caused by the snow separating and crowding it to the outside, is entirely avoided. As will be seen, the snow enters unmolested into the space I until it passes that point where the paddles are already tilled with snow cut by the knives J, the core of the snow thus passing into the space I and traveling up, after being cut by the cutting-bars L, the cone K to the rear of the paddles to be discharged, as previously mentioned. The snow entering the casing It at the bottom N also passes to the rear of the casing to be operated on by the paddles II at their rear ends to be carried up and discharged through the opening F, as previously described. The strain is thus removed from the center of the wheel, whereby the latter can operate with greater freedom and discharge the snow at a high rate of speed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a rotary snow-plow, a wheel com prising a back plate mounted to turn, a series of paddles extending radially and at right angles from the front face of the said back plate, the apexes of the paddles terminating near the center of the back plate and arranged parallel to the axis of the wheel, so as to form a central space on the faceof the said back plate, and a cone secured with its base centrally on the face of the said back plate and extending freely into the said central space, substantially as shown and described.

2. In a rotary snow-plow, the combination, with a casing, of a wheel mounted to turn therein and comprising a back plate, a series of paddles extending radially and at right angles from the front face of the said back plate, the apexes of the paddles terminating near the center of the back plate and arranged parallel to the axis of the wheel, so as to form a central space on the face of the said back plate, and a cone secured with its base centrally on the face of the said back plate and extending freely into the said central space, substantially as shown and described.

3. In a rotary snow-plow, a wheel comprising a back plate mounted to turn, a series of paddles extending radially and at right angles from the front face of the said back plate and terminating near the center of the back plate to form a central space in the wheel, and reversible cutters held on the front ends of the said paddles, substantially as shown and described.

1-. In a rotary snow-plow, a wheel com prising a circular back plate mounted to turn, a series of wedge-shaped paddles extending ra' dially and at right angles from the face of the said back plate,the apexes of the paddles terminating near the center of the back plate, so as to form a central space in the wheel, and reversible cutters held 011 the front ends of the said paddles, substantially as shown and described.

In a rotary snow-plow, a wheel comprising a back plate mounted to turn, a series of paddles extending radially and at right angles from the front face of the said back plate and terminating near the center of the said back plate to form a central space in the wheel, a cone secured with its base centrally on the face of the said backplate and extending into the said central space, and reversible cutters held on the front ends of the said paddles, substantially as shown and described.

6. In a rotary snow-plow, a wheel comprising a circular back plate mounted to turn, a series of wedge-sl'iaped paddles extending radially and at right angles from the face of the said back plate, the apexes of the paddles terininatingnear the centerof the back plate, so as to form a central space in the wheel, and radially-arrangcd cutters connecting with the apexes of the said wedge-shaped paddles and located at or near the middle of the same, substantially as shown and described.

7. In a rotary snow-plow, a wheel comprising a back plate mounted to turn, a series of paddles extending radially and at right angles from the front face of the said back plate and terminating near the center of the back plate to form a central space in the wheel, a cone secured with its base centrally on the face of the said back plate and extending into the said central space, and radially-arranged cutters extending from near the apex of the said cone to the apexes of the said wedgeshaped cutters, substantially as shown and described.

8. In a rotary snow-plow, a circular casing open in the front and cut out at the bottom of its rim, and a horizontal bottom arranged below the cutout part of the rim, substantially as described, so as to deliver the snow near the ground to the rear of the casing, as set forth.

5). In a rotary snow-plow, a circular casing open in the front and cut out at the bottom of its rim, a horizontal bottom arranged be low the cut-out part of the rim, substantially as described, so as to deliver the snow near the ground to the rear of the casing, and gussets arranged in the sides of the said bottom and leading up at their inner ends to the cutout part of the rim, substantially as shown and described.
